Abstract
A process for producing liquid and, optionally, gaseous products from gaseous reactants includes feeding, at a low level, gaseous reactants into a slurry bed, allowing the gaseous reactants to react as they pass upwardly through the slurry bed, withdrawing any gaseous product and unreacted gaseous reactants from a head space above the slurry bed and withdrawing liquid product and/or slurry bed to maintain the slurry bed at a desired level. The process further includes passing boiler water, as a first heat transfer fluid, in indirect heat exchange relationship through the slurry bed to remove heat from the slurry bed, allowing the heated boiler water to flash and separate to form pressurised steam, controlling the pressure of the steam to be substantially constant, and passing a second heat transfer fluid in indirect heat exchange relationship through the slurry bed to remove heat from the slurry bed.
